Real VSI+$40+1hour=working real VSI gauge!

[727737Nut]

Hi all,
Well i wish it was all this easy but reality knows it isn't.   Now this particular gauge was.

I bought for 24.95 off of ebay,looks unused and brand new! 

Any way, if you look close, it is driven by a small dc motor and has a potentiometer for position feedback. Sound familiar???  SERVO!!!!!!!!!!!!!!!!     Soooo, i took an old traxxes servo from an old rc car, desoldered the motor, cut off the pot. I then solder leads from the gauge motor to the servo pcb were the original motor was. Then i used a simple servo lead soldered to the pot in the gauge and simply plugged it into the legs of the pot that was cut off of the servo pcb.  Then plugged the "new" servo into the OC servo board and a quick SIOC program. PRESTO!!! A perfectly working smooth as melted butter operating real 737 or 727 VSI gauge.  This was way to easy!  But cool none the less.  See attached pics, any questions feel free to ask.

Very nicely done...  It got a bit confusing but I think I understood.  So you ripped apart your Traxxas Servo, (Just for the motor?) and installed just that motor in the gauge housing? and then control the Servo motor by the SIOC Servo Card?  And you used the existing pot to provide feedback to the "Traxxas" controller?

LOL.  perhaps it is just too  early in the morning..  Regardless it looks awesome.

LOL,
Sorry i should have taken more pics.  I used the existing motor and pot in the gauge and just the control circuit of the servo. Works unbelievably well!

LOL.  Awesome, that makes perfect sense now

Thanks Rob,
